Heat Pumps in Portsmouth NH and surrounding areas


HVAC systems specialize in transporting warm air wherever it is needed – outside in the summer and inside in the winter. But when your heat pump isn’t working, it can cause major home comfort issues. Depending on the temperature and weather outside, being without heat can even potentially be dangerous. When your heat pump dies on you at the worst possible time, let CMC Mechanical Services LLC help you with our heat pump repair service.


Heat pumps work double duty throughout the year because they provide both warm and cold air. All of this extra use can cause them to wear out and need professional heat pump repairs. The heating and cooling experts at CMC Mechanical Services LLC are proud to provide 24/7 emergency service in Portsmouth NH and surrounding areas for heat pump repair and services for all makes and models. If your heat pump has any issues, give us a call and one of our friendly experts will help you.


Many New Hampshire homeowners automatically think of a furnace and air conditioner when it comes to heating and cooling their homes. But a heat pump is an extremely efficient and reliable choice to successfully achieve the level of comfort you want for your home. Here is why:

  • You buy just one unit instead of separate heating and cooling equipment, which means you typically will spend less money on installation and maintenance.
  • A heat pump does not burn fossil fuels like a furnace does, which means low energy consumption and a reduction in carbon emissions.
  • It can cut your electricity use for heating in half when compared to an electric furnace.


Our CMC Mechanical Services LLC experts can install a heat pump to serve as the central HVAC unit in your Portsmouth NH and surrounding areas home. A single, central heat pump system relies on air ducts to circulate hot and cold air throughout your home, just as a furnace and air conditioner do.

When working with your air ducts, be sure to consider if you need to help improve your indoor air quality, especially if you have someone in your home with chronic respiratory illnesses or allergies. We have several indoor air quality systems we can implement with your heat pump and air ducts. Also, take the time to talk with our team about duct cleaning to rid your home of the possible pollutants in your ducts.

If you prefer several ductless heat pump systems, rather than one central unit, we can help with that as well. These compact units are installed throughout your home and are a great solution for rooms without air ducts.

When it comes to heat pumps, another possibility is adding a heat pump to your existing HVAC system to improve heating efficiency. This is known as a dual-fuel system, consisting of a furnace and a heat pump working as a team to heat your home. The heat pump serves as your primary heating source until the temperature drops too low for it to work at peak performance. At that point, the furnace kicks in and continues heating until the heat pump can take over again.

We can also help you with financing. Whether you are looking to add a more traditional heat pump, a ductless system, or a dual-fuel system, we have options to fit your particular needs.


Call us if your heat pump stops working or if the air in your home does not feel as hot or cold as it should. Our highly trained HVAC professionals have the experience to get your heating and cooling system back on track.

We provide prompt repair service, and we pride ourselves on our workmanship. Our company values honesty and integrity. We will never attempt to sell you something you do not need or take shortcuts in anything we do. At CMC Mechanical Services LLC, you can trust the parts and materials we use are the best and will last. When we make a repair, it stays repaired.


By performing biannual inspections and tune-ups, CMC Mechanical Services LLC can help you avoid inconvenient and costly equipment breakdowns, refrigerant leaks, and compressor problems. Your heat pump will last longer and will perform more efficiently if it is maintained on a regular basis by professionals. It will also keep you compliant with your manufacturer’s warranty.


What is the average life span of a heat pump?
Heat pumps can normally last, on average, up to 15 years. Of course, this projected life expectancy is contingent upon the type of heat pump you choose and how well you professionally maintain it.

Do heat pumps work well in the winter?
Yes, heat pumps can heat your home very well throughout the winter. Years ago, heat pumps could only heat down to a specific temperature close to freezing. Now the high energy-efficient models can heat throughout the winter, especially here in the Portsmouth NH and surrounding areas. But our HVAC experts can assess if a dual-fuel system would work better for your individual needs.

Does my heat pump have a filter?
Yes, your heat pump has a filter, and you need to change it regularly like you do for a furnace. Your air filter directly affects your home’s indoor air quality, so our professionals recommend changing it every three months. If you have someone in your home with asthma, allergies, or other respiratory conditions, or if you have a smoker or pets, you probably need to change it even more frequently.
